Supported Targets	ESP32-H2

OpenThread Command Line Example

This example demonstrates an OpenThread CLI, with some additional features such as TCP, UDP and Iperf.

How to use example

Hardware Required

To run this example, an ESP32-H2 board is required.

Configure the project

idf.py menuconfig

The example can run with the default configuration.

Build, Flash, and Run

Build the project and flash it to the board, then run monitor tool to view serial output:

idf.py -p PORT build flash monitor

Now you'll get an OpenThread command line shell.

Example Output

The help command will print all of the supported commands.

Set Up Network

To run this example, at least two ESP32-H2 boards flashed with this ot_cli example are required.

On the first device, run the following commands:

> factoryreset
... # the device will reboot

> dataset init new
Done
> dataset commit active
Done
> ifconfig up
Done
> thread start
Done

# After some seconds

> state
leader
Done

Now the first device has formed a Thread network as a leader. Get some information which will be used in next steps:

> ipaddr
fdde:ad00:beef:0:0:ff:fe00:fc00
fdde:ad00:beef:0:0:ff:fe00:8000
fdde:ad00:beef:0:a7c6:6311:9c8c:271b
fe80:0:0:0:5c27:a723:7115:c8f8

# Get the Active Dataset
> dataset active -x
0e080000000000010000000300001835060004001fffe00208fe7bb701f5f1125d0708fd75cbde7c6647bd0510b3914792d44f45b6c7d76eb9306eec94030f4f70656e5468726561642d35383332010258320410e35c581af5029b054fc904a24c2b27700c0402a0fff8

On the second device, set the active dataset from leader, and start Thread interface:

> factoryreset
... # the device will reboot

> dataset set active 0e080000000000010000000300001835060004001fffe00208fe7bb701f5f1125d0708fd75cbde7c6647bd0510b3914792d44f45b6c7d76eb9306eec94030f4f70656e5468726561642d35383332010258320410e35c581af5029b054fc904a24c2b27700c0402a0fff8
> ifconfig up
Done
> thread start
Done

# After some seconds

> state
router  # child is also a valid state
Done

The second device has joined the Thread network as a router (or a child).

TCP and UDP Example

On the leader device, start a TCP or UDP server:

> tcpsockserver
Done
I (1310225) ot_socket: Socket created
I (1310225) ot_socket: Socket bound, port 12345
I (1310225) ot_socket: Socket listening, timeout is 30 seconds

or (UDP Server)

> udpsockserver
Done
I (1339815) ot_socket: Socket created
I (1339815) ot_socket: Socket bound, port 54321
I (1339815) ot_socket: Waiting for data, timeout is 30 seconds
Done

On router device, start a TCP or UDP client (replace with the leader's IPv6 address):

> tcpsockclient fdde:ad00:beef:0:a7c6:6311:9c8c:271b
Done
ot_socket: Socket created, connecting to fdde:ad00:beef:0:a7c6:6311:9c8c:271b:12345
ot_socket: Successfully connected
...

or (UDP Client)

> udpsockclient fdde:ad00:beef:0:a7c6:6311:9c8c:271b
Done
ot_socket: Socket created, sending to fdde:ad00:beef:0:a7c6:6311:9c8c:271b:54321
ot_socket: Message sent
...

Iperf Example

Print the iperf help:

iperf
---iperf parameter---
-s                  :     server mode, only receive
-u                  :     upd mode
-V                  :     use IPV6 address  
-c <addr>           :     client mode, only transmit
-i <interval>       :     seconds between periodic bandwidth reports
-t <time>           :     time in seconds to transmit for (default 10 secs)
-p <port>           :     server port to listen on/connect to
-l <len_send_buf>   :     the lenth of send buffer
---example---
create a tcp server :     iperf -s -i 3 -p 5001 -t 60 
create a udp client :     iperf -c <addr> -u -i 3 -t 60 -p 5001 -l 512
Done

On the leader device, start iperf TCP or UDP server:

> iperf -V -s -i 3 -p 5001 -t 20
i:3
dp:5001
sp:5001
t:20
Done

or (UDP Server)

> iperf -V -s -u -i 3 -p 5001 -t 20
i:3
dp:5001
sp:5001
t:20
Done

On the router device, start iperf TCP or UDP client:

> iperf -V -c fdde:ad00:beef:0:a7c6:6311:9c8c:271b -i 1 -t 5 -p 5001 -l 85
ip:fdde:ad00:beef:0:a7c6:6311:9c8c:271b
